I've already thought about using the Sky plugin (or some derivative of
that, implementing a dummy device) for this purpose. When you're not
live-viewing, tune to a special channel which uses this device for
input. This will switch off the primary device, _IF_ that is a
documented feature - is it?

This is easy to implement: assume you're using xawtv, make a start
script like this:

svdrpsend.pl chan 1
xawtv &

and a stop script like this:
killall xawtv
svdrpsend.pl chan 9999

and call them alternating at the "power" button of your remote via irexec.
For software devices, e.g. substitute xine for xawtv, should work similarly.
Extend at will to remember the currently tuned live-view channel in a file.

(I've read that the part which consumes most energy and produces most
heat is the frontend, which sounds reasonable given that it has to
power the LNB - at least for DVB-S - but the problem is the same: turn
off the device if not used.)
